First Tesla Semi Charging Station Opens to the Public

Tesla took another step toward commercializing heavy-duty electric trucking in the United States. Tesla Energy has activated its first public Semi Supercharger, a Megawatt Charging System (MCS) site, in the Greater Los Angeles area, and it is now open to Tesla Semi customers. These MCS stations resemble V4 Superchargers but use the MCS connector, which is exclusive to the Tesla Semi.

Located in Ontario, California, the new public charging hub marks a major operational milestone for the Tesla Semi program. Until now, Tesla Semis have primarily charged on private, closed-loop routes.

First Public Pull-Through Hub

According to Tesla’s charging map, the Megacharger is at 4265 E Guasti Rd in Ontario, close to the airport. The site can deliver up to 750 kW of power to Semis.

This 750 kW output matches the charging hardware at private, early-adopter facilities like PepsiCo's Sacramento depot. At those speeds, the Semi can be topped up in under 45 minutes, significantly reducing downtime for fleet operators.

The BP Pulse Partnership

This first public Semi charger is co-located at BP Pulse's brand-new, ultra-fast electric truck charging depot rather than being a standalone, Tesla-branded Supercharger lot.

The site operates as a multi-platform commercial charging hub for Southern California logistics routes. According to BP Pulse, the Ontario location includes two 750 kW Tesla MCS pull-through bays exclusively for the Semi, alongside four 400 kW CCS pull-through bays designed for other electric heavy-duty trucks from legacy automakers.

The MCS bays are currently reserved for the Semi but are expected to open to other brands. Tesla’s Semi is not equipped with CCS ports, and there is currently no CCS to MCS adapter, so it cannot use the CCS bays.

Another Milestone for Semi

Until now, the Tesla Semi has been largely tied to private infrastructure. The only active Megachargers were behind closed gates at corporate customer facilities or at Tesla's factory locations in Nevada and Lathrop.

With public, highway-adjacent Megachargers coming online, Tesla is laying the groundwork for long-haul, interstate trucking. With volume production of the Semi targeted for 2026 at the newly expanded Giga Nevada facility, rapid deployment of the public MCS network will be a critical factor in whether major fleet operators adopt the truck at scale.
